Hammar H20 EPIRB for EPIRBS



The Hammar H20 EPIRB HRU is a hydrostatic release unit designed to be safe and reliable in all extreme conditions that you and your ship might meet on the oceans. Should the vessel sink, the Hammar H20, which is activated by increasing water pressure, will automatically release liferafts and EPIRBs.

The construction of glass fibre reinforced nylon prevents the Hammar H20 from corroding, which means that no annual service, maintenance or spare parts are needed. You simply install a new one every two years and dispose of the old one.

- As under Hammar EPIRB hydrostatic release unit part no: 82-962-001A
- Suits all McMurdo EPIRB's as well as Pains Wessex, Graseby, Newcom and Nova Rescue EPIRB's
- Release the EPIRB after 1.5m - 4m submerged.

In an emergency situation the automatically activation of the EPIRB will dramatically facilitate the rescue operation and the possibility to save lives. The Hammar H20 is the most reliable hydrostatic release unit on the market and is used by most leading EPIRB manufactures.

The Hammar H20 is widely used for Emergency Position Indicating Radio Beacons (EPIRB). 90% of the world’s EPIRB manufacturers are using the Hammar H20 for the free float function. Should the vessel sink, the Hammar H20, which is activated by increasing water pressure, automatically release the EPIRB. On reaching the surface the EPIRB starts to emit a signal of identification and position to a satellite. Instead of the rope sling a specially developed plastic bolt secures the radio beacon and will be cut when the unit is activated.




Whether you are a ship owner, designer, builder or onboard safety officer, Hammar Remote Release Systems offer flexible solutions with many distinct advantages in terms of safety and cost.

Saving lives
Thanks to a remote triggering system, lifesaving and other equipment can be released from the bridge or other strategic locations onboard. This means that in an emergency situation, you can save precious time. Furthermore, the release mechanism can be deployed irrespective of parameters such as weather, smoke, fire or degree of list to one side, without the crew having to take any unnecessary risks.

Financial benefits
The systems not only improve safety onboard, they also represent a sound economic investment. Liferafts can be positioned in remote locations onboard and valuable deck surface can be freed for passengers or cargo to increase profitability. Since the systems are easy to handle, you can also minimise both crew and training costs.

Optimising work onboard
Besides saving lives and improving economy, the systems can simplify work onboard in many areas. Closing and opening doors or releasing buoy systems, maintenance equipment and other heavy loads up to 1 ton, are just a few of many possible applications. You get a head start by planning for Hammar Remote Release Systems from the initial design stage, but the systems can also be retro-fitted.

Choose between two different systems
MRRS - Manual Remote Release System (vacuum)
ERRS - Electronic Remote Release System

Both ERRS and MRRS are tested and approved to recognized marine standards.
